Answer: 18% of all students in the eighth grade at Lincoln Junior High School have pancakes as their

favorite breakfast, but we cannot conclude anything about the percent of the population who have

breakfast as their favorite meal.

Step-by-step explanation: A is incoorect 18% of all students at Lincoln Junior High School have breakfast as their favorite meal. As they only surveyed 8th grade students on their favorite breakfast we cannot say anthing for the rest of the school.

As for the second answer choice it asks what they like for breakfast not the favorite meal.

Hope this helps.

If −5e^x^2 y=x and y(−5)=0, find y′(−5) by implicit differentiation

xenn [34]

Differentiate:
-5×2(xe^x^2)y-5e^x^2dy/dx=1
-5e^x^2(2xy+y´)=1
When x=-5, y=0:
-5e²⁵y´=1, so y´(-5)=-eˉ²⁵/5

I am so confused! Can anyone help me with this trig problem?

Dominik [7]

$\frac{5\pi }{4}$ or $\frac{7\pi }{4}$

divide both sides by 2

sinΘ = - $\frac{\sqrt{2} }{2}$

Since the sin ratio is negative then Θ is in third / fourth quadrants

Θ = $sin^{- 1}$ ( $\frac{\sqrt{2} }{2}$ ) = $\frac{\pi }{4}$ related acute angle

Θ = ( π + $\frac{\pi }{4}$ ) = $\frac{5\pi }{4}$

or Θ = ( 2π - $\frac{\pi }{4}$ ) = $\frac{7\pi }{4}$

Answer:

Mean = sum of all elements/number of elements

= (7.5 + 10.5 + 5 + 4.5 + 3.5 + 7.5 + 4 + 10 + 7.5 + 5)/10

= 6.5

=> Option C is correct

Hope this helps!

I have no idea how to do this please help

$\begin{gathered} a)slope\colon7 \\ b)y-intercept\colon-6 \end{gathered}$

1) As we can see this is a Linear Equation written in the Slope-intercept form:

$y=mx+b$

Note that "m" stands for the slope of the line, i.e. the measure of how steep a line is.

In the given equation, we can state that the slope is always accompanying the "x" therefore, the slope is m= 7

2) In addition to this, the y-intercept also called the Linear Coefficient is given by the letter"b" and represents the y-coordinate that the graph intercepts. Thus the y-intercept is -6

So we can state the following as the answers:

$\begin{gathered} a)slope\colon7 \\ b)y-intercept\colon-6 \end{gathered}$

And that is the answer
